Description

Technical Field

[0001] The present invention relates to the technical field of cable maintenance equipment, and particularly to a multifunctional maintenance equipment for power station electrical equipment. Background Art

[0002] In the initial stage of the development of the power industry, the scale of power stations was relatively small, the power transmission distance was short, and the requirements for cables and wires were relatively simple. At that time, the conductor materials mainly relied on copper and aluminum, which became the mainstream choice due to their good electrical conductivity. The insulation layers of cables mostly used rubber or simple plastic materials. This insulation method could prevent electric leakage to a certain extent, but it had obvious deficiencies in high temperature resistance, high voltage resistance, and durability. For example, rubber-insulated cables were prone to aging and cracking in a long-term high-temperature environment, resulting in a decline in insulation performance and threatening the safe operation of power stations.

[0003] With the gradual expansion of the scale of power stations, especially the construction of large-scale hydropower stations, thermal power stations, and nuclear power stations, the performance requirements for cables and wires have increased sharply. Higher voltage levels and larger transmission capacities have become urgent problems to be solved. Therefore, the cross-linked polyethylene insulation technology emerged and was widely used. XLPE has excellent electrical insulation performance and can withstand higher voltages without being broken down. At the same time, it has good thermal stability and can operate at a relatively high temperature for a long time, greatly improving the current-carrying capacity of cables. In terms of conductor structure, in order to reduce the AC resistance loss, the compacted conductor process began to be adopted, making the conductor more compact, reducing the gaps between conductors, and thus improving the conduction efficiency.

[0004] During the use of cables and wires, due to length or damage problems, it is often necessary for staff to splice the joints of two cables. When splicing the joints of two cables, first, the staff needs to connect the metal wires at the joints of the two cables, then wind the connection position of the wires with insulating tape, and finally wrap and wind the insulating sleeves at the positions of the two cable joints. However, this splicing and maintenance method for cables and wires has poor effects. Over time, the adhesive on the insulating tape will gradually fail, and gaps will appear at the joints of the metal wires wrapped with the insulating tape. Dust and moisture in the external environment will enter the connection of the metal wires through the gaps, resulting in problems such as short circuits or increased power loss during power transmission. Therefore, those skilled in the art have proposed a multifunctional maintenance equipment for power station electrical equipment to solve the above-mentioned technical problems. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a multifunctional maintenance equipment for power station electrical equipment, which solves the problem that dust and moisture in the external environment enter the connection of metal wires through the gaps of insulating tapes, resulting in short circuits or increased power loss during power transmission.

A plurality of inner buckle cavities are circumferentially arranged near the edge of the outer wall of the outer buckle plate. A magnetic attraction layer is arranged at the edge of the outer buckle plate.

[0014] Preferably, the sheath splicing mechanism includes a metal sleeve. A metal sleeve is arranged between two lower support bases. Installation ring seats are arranged on both sides in the middle of the inner wall of the metal sleeve. Sealing ring seats are arranged in the middle of the inner side of each installation ring seat. A repair cavity is formed between the sealing ring seats. A first injection pipe is arranged in the middle of one side of the outer wall of the metal sleeve, and the inside of the first injection pipe is communicated with the inside of the repair cavity. A rotating cover is arranged at the top of the first injection pipe.

[0015] Preferably, the end support mechanism includes a lifting seat. Lifting seats are provided on the tops of the lower support seats. Annular cavities are formed in the middles of the adjacent sides of the lifting seats and the lower support seats. Rubber ring seats are provided on the inner walls of the annular cavities. On both sides of the middle of the top end of the lower support seat, vertical adjusting rods are provided, and the tops of the vertical adjusting rods penetrate through the lifting seats and extend outwards. Locking nuts are threadedly connected to the vertical adjusting rods.

[0016] Preferably, the end support mechanism further includes a horizontal adjusting rod. Horizontal adjusting rods are provided on the upper and lower sides between the lifting seat and the lower support seat. The two ends of the horizontal adjusting rod penetrate through the corresponding positions of the lifting seat and the lower support seat and extend outwards respectively. Adjusting nuts are threadedly connected to the two ends of the horizontal adjusting rod. Holding cavities are formed in the upper middles of the lifting seats.

[0017] Preferably, the repair and shaping mechanism includes aluminum alloy fins. A plurality of aluminum alloy fins are equidistantly and fixedly connected to the middles of both sides of the outer wall of the metal sleeve. An acceleration cavity is formed between adjacent aluminum alloy fins. Arc-shaped metal plates are provided on the middles of both sides of the outer wall of the metal sleeve, and the inner walls of the arc-shaped metal plates are respectively connected to the aluminum alloy fins at the corresponding positions. The inside of the arc-shaped metal plate is a hollow cavity.

[0018] Preferably, the joint seat is located in the middle of the metal sleeve, and the brightness of the metal sleeve abuts against the rubber ring seat.

[0019] Working principle: When splicing the cables of electrical equipment in a power station, first, the staff install the upper lifting seats and lower supporting seats at both ends of the overall device at both ends of the spliced cable respectively. Then, the metal sleeve between the two is also sleeved onto one of the cables. After that, the joint seat inside the metal sleeve is taken out to complete the preparatory work before the equipment is used. Then, the separation and repair mechanism is started. First, the staff insert the ends of each metal wire inside one cable into it through the guide of the insertion tube on the joint seat. Then, the staff remove the outer buckle plate on the joint seat. After that, the metal wires on the other cable are inserted through the sockets on the outer buckle plate and the stepped ring plate. After the outer buckle plate is sleeved onto the other cable, the staff use tools to kink and connect the corresponding metal wires inside the two cables. After the metal wires inside the two cables are connected, the staff reset the outer buckle plate. When the outer buckle plate is reset, it adsorbs to the joint seat through the magnetic adsorption layer on it to ensure the sealing performance of the joint seat during use, so that the outer buckle plate on the joint seat seals its interior. Then, the staff open the sealing cover on the second injection pipe and inject the melted insulating repair material into the flow cavity through the second injection pipe on the joint seat. Then, as the insulating repair material in the flow cavity is continuously injected, the insulating repair material in the flow cavity flows into the insertion tube, so as to seal the connection of the metal wires again with insulating material. Then, the repair material flowing into the insertion tube is prevented from overflowing through the silica gel countercurrent ring in the insertion tube. At the same time, the stepped ring plate in the socket can also prevent the insulating repair material from overflowing. After the connection of the metal wires is repaired and shaped, the staff remove the joint seat and the outer buckle plate, and then peel off the excess material at the repair place to complete the separation and repair treatment of the connection of the metal wires. Then, the sheath splicing mechanism is started. After the separation and repair mechanism repairs the connection of the two metal wires, the staff move the metal sleeve sleeved on the cable to the position where the two cables are connected. After the metal sleeve moves to the repaired position, the sealing ring seat on the installation ring seat seals both sides of the repaired position. Then, the staff open the rotating cover on the first injection pipe and inject the melted insulating repair material into the repair cavity in the metal sleeve through the rotating cover. The insulating repair material flowing in the repair cavity repairs the insulating skin part on the outer surface of the connection position of the two cables, thus completing the splicing operation of the insulating sheaths after the two cables.Meanwhile, the end support mechanism is activated. First, the staff installs the lifting seat on the lower support seat, and then rotates the locking nut on the vertical adjustment rod to squeeze the lifting seat to move downward towards the lower support seat. While the lifting seat approaches the lower support seat, the rubber ring seat in the annular cavity squeezes and fixes the outer wall of the cable. Repeat the above operation to fix the other section of the cable in the same way. Then, the staff connects the lifting seats and lower support seats at both ends of the cable through the horizontal adjustment rod and fixes them with the adjustment nuts at both ends of the horizontal adjustment rod to ensure that the position where the sheath splicing mechanism repairs the outer insulation layer at the connection of the two sections of the cable is in a horizontal state. At the same time, it can also prevent the repaired position from being affected by external forces, thus completing the end support treatment of the two sections of the cable. After that, the repair and shaping mechanism is activated. When the sheath splicing mechanism repairs the insulation layers on the outer walls of the two sections of the cable, the high-temperature repair material in the repair cavity conducts its internal high temperature out into the external environment through the metal sleeve, thereby accelerating its shaping in the first step. Then, the temperature and heat conducted out of the material in the repair cavity to the outside are absorbed by the aluminum alloy fins outside the metal sleeve and then conducted to the arc-shaped metal plate on the same side again, so as to expand its heat dissipation area. And because the acceleration cavities formed between adjacent aluminum alloy fins can accelerate the speed of air passing through the external environment, the heat generated by the repair material in the repair cavity can be taken away to the greatest extent by the accelerating air flow, thereby promoting the shaping of the cable repair position.

[0020] The present invention provides a multifunctional maintenance device for power station electrical equipment. It has the following beneficial effects:

[0021] 1. By adding and setting the separation and fixation mechanism, the present invention can seal and fix the connection of metal wires in the cable in a unique way of separation and fixation. This method effectively avoids problems such as wire displacement and poor contact that may occur in the traditional connection method, greatly enhancing the stability and reliability of the connection. Subsequently, the connection is sealed and wrapped for repair with the melted repair material, further strengthening the tightness of the connection part, effectively preventing impurities such as water vapor and dust from invading, significantly extending the service life of the cable, reducing the maintenance cost and failure rate, and ensuring the high efficiency and safety of power transmission.

[0022] 2. By adding and setting the sheath splicing mechanism, after the connection repair of the metal wires of the cable is completed, the melted insulating material is used to splice and repair the sheaths at the connection of the two sections of the cable. This method can efficiently restore the integrity of the cable sheath, effectively block the physical wear, chemical corrosion and invasion of the humid environment from the outside to the inside of the cable. Moreover, this repair method can not only enhance the stability of the overall structure of the cable, but also ensure that the insulation performance of the cable is not damaged, greatly reducing the potential safety hazards caused by sheath damage, extending the service life of the cable, improving the safety and reliability of cable operation, and reducing the frequency and cost of cable maintenance and replacement.

[0023] 3. By adding and setting an end support mechanism, when repairing the sheath at the connection of two sections of cables, this mechanism supports and fixes both ends of the repair position to ensure that the cable is in a horizontal state. This stability guarantees the accuracy of the repair operation, effectively avoiding problems such as uneven distribution of repair materials or loose connections caused by cable shaking and offset. Moreover, the horizontal state is conducive to the uniform flow and curing of the repair materials, improving the sheath repair quality, making the appearance of the repaired cable flat and the structure stable. At the same time, it can also reduce potential safety hazards caused by improper repair, improve the cable repair efficiency, reduce labor and time costs, and lay a foundation for the long-term stable operation of the cable.

[0024] 4. By adding and setting a repair shaping mechanism, when repairing the splicing of the sheaths of two sections of cables, its unique multi-heat conduction design can quickly dissipate the heat of the repair materials to the external environment, effectively accelerating the shaping of the repair materials, significantly shortening the repair time, and improving work efficiency. At the same time, by accelerating air flow to carry away the conducted heat, the heat dissipation effect is further optimized, making the shaping process more stable and reliable. This method not only guarantees the strength and sealing performance of the repaired sheath, reducing defects caused by poor shaping, but also enables the cable to be put into use faster, reducing the thermal impact on the surrounding environment, and enhancing the overall performance and practicality of the cable repair process.

Detailed implementation manner

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to the appendix Figure 1 - appendix Figure 8 , the embodiment of the present invention provides a multifunctional maintenance device for power station power equipment, including a lower support seat 13, which serves as the basic component of the overall device and is used for assembling and carrying each processing mechanism and its subordinate structural components; a joint seat 16 is located in the middle of the metal sleeve 5, and the brightness of the metal sleeve 5 abuts against the rubber ring seat 2.

[0036] A separation and repair mechanism is arranged in the middle between two lower support seats 13 and is used for separating and sealing and repairing the metal wire connection part between two sections of cables;

[0037] The separation and repair mechanism includes a joint seat 16. A joint seat 16 is arranged between two lower support seats 13. A concave seat 24 is arranged on one side of the inner side of the joint seat 16. An outer buckle plate 17 is arranged on one side of the joint seat 16. A plurality of wire inserting pipes 26 are circumferentially arranged on the side of the joint seat 16 away from the outer buckle plate 17, and one end of the wire inserting pipe 26 penetrates through the concave seat 24 and extends outward. Silicone countercurrent rings 27 are arranged in the middle of the inner walls of the wire inserting pipes 26. The concave seat 24, the inner wall of the joint seat 16 and the inner wall of the outer buckle plate 17 form a flow cavity 25.

[0038] When the separation and repair mechanism is started, first, the staff inserts the ends of the metal wires within a section of cable into the inside of the insertion tube 26 on the joint seat 16 through the guidance of the insertion tube 26. Then, the staff removes the outer buckle plate 17 on the joint seat 16. After that, the metal wires on the other section of cable are inserted through the socket 20 on the outer buckle plate 17 and the stepped ring plate 29. After the outer buckle plate 17 is sleeved on the other section of cable, the staff uses tools to twist and connect the corresponding metal wires within the two sections of cable.

[0039] The separation and repair mechanism further includes a second injection tube 19. The middle of the top of the outer wall of the joint seat 16 is provided with the second injection tube 19, and the inside of the second injection tube 19 is communicated with the inside of the flow cavity 25. The upper part of the second injection tube 19 is threadedly connected with a sealing cover 22. The middle of the inner side of the outer buckle plate 17 is fixedly connected with a stepped ring plate 29. A plurality of sockets 20 are circumferentially arranged in the middle of the outer buckle plate 17 and the stepped ring plate 29. Silicone layers 28 are arranged on the inner walls of the sockets 20. A plurality of inner buckle cavities 23 are circumferentially arranged near the edge of the outer wall of the outer buckle plate 17. A magnetic adsorption layer 30 is arranged at the edge of the outer buckle plate 17.

[0040] After the metal wires within the two sections of cable are connected, the staff resets the outer buckle plate 17. While the outer buckle plate 17 is being reset, it is adsorbed to the joint seat 16 through the magnetic adsorption layer 30 thereon, so as to ensure the sealing performance of the joint seat 16 during use, so that the outer buckle plate 17 on the joint seat 16 closes its inside. Then, the staff opens the sealing cover 22 on the second injection tube 19 and injects the melted insulating repair material into the flow cavity 25 through the second injection tube 19 on the joint seat 16.

[0041] Then, as the insulating repair material in the flow cavity 25 is continuously injected, the insulating repair material in the flow cavity 25 flows into the insertion tube 26, so as to seal the connection of the metal wires again with insulating material. Then, the repair material flowing into the insertion tube 26 is prevented from overflowing through the silicone countercurrent ring 27 in the insertion tube 26. At the same time, the stepped ring plate 29 in the socket 20 can also prevent the overflow of the insulating repair material. After the connection of the metal wires is repaired and shaped, the staff removes the joint seat 16 and the outer buckle plate 17, and then peels off the excess material at the repair place, so as to complete the separation and repair treatment of the connection of the metal wires.

[0042] The sheath splicing mechanism is arranged between the two lower brackets 13 and is used for splicing the sheaths at the end connections of the two sections of cable.

[0043] The sheath splicing mechanism includes a metal sleeve 5. A metal sleeve 5 is arranged between the lower support seats 13. Installation ring seats 14 are arranged on both sides of the middle part of the inner wall of the metal sleeve 5. Sealing ring seats 18 are arranged in the middle of the inner sides of the installation ring seats 14. A repair cavity 15 is formed between the sealing ring seats 18. A first injection pipe 12 is arranged in the middle of one side of the outer wall of the metal sleeve 5, and the inside of the first injection pipe 12 is communicated with the inside of the repair cavity 15. A rotating cover 21 is arranged at the top of the first injection pipe 12.

[0044] When the sheath splicing mechanism is started, after the connection part of the two metal wires is repaired by the separating and repairing mechanism, the staff moves the metal sleeve 5 sleeved on the cable to the position where the two cables are connected. After the metal sleeve 5 moves to the position to be repaired, the sealing ring seats 18 on the installation ring seats 14 seal both sides of the repair position. Then the staff opens the rotating cover 21 on the first injection pipe 12 and injects the melted insulating repair material into the repair cavity 15 in the metal sleeve 5 through the rotating cover 21. The insulating repair material flowing in the repair cavity 15 repairs the insulating skin part on the outer surface of the connection position of the two cables, thus completing the splicing operation of the insulating sheaths of the two cables.

[0045] The end support mechanism is arranged on the lower support seat 13 and is used for supporting and preventing deformation of both sides of the cable after the sheath splicing mechanism performs splicing treatment.

[0046] The end support mechanism includes a lifting seat 1. Lifting seats 1 are arranged on the tops of the lower support seats 13. Annular cavities 3 are respectively arranged in the middle of the adjacent sides of the lifting seats 1 and the lower support seats 13. Rubber ring seats 2 are arranged on the inner walls of the annular cavities 3. Vertical adjusting rods 7 are respectively arranged on both sides of the middle part of the top end of the lower support seat 13, and the top ends of the vertical adjusting rods 7 penetrate through the lifting seats 1 and extend outwards. Locking nuts 8 are threadedly connected to the vertical adjusting rods 7.

[0047] The end support mechanism further includes a horizontal adjusting rod 10. Horizontal adjusting rods 10 are arranged on the upper and lower sides between the lifting seats 1 and the lower support seats 13, and the two ends of the horizontal adjusting rods 10 respectively penetrate through the corresponding positions of the lifting seats 1 and the lower support seats 13 and extend outwards. Adjusting nuts 6 are threadedly connected to both ends of the horizontal adjusting rods 10. Holding cavities 11 are respectively arranged in the upper middle parts of the lifting seats 1.

[0048] When the end support mechanism is started, the staff first installs the lifting seat 1 on the lower support seat 13, and then rotates the locking nut 8 on the vertical adjusting rod 7 to squeeze the lifting seat 1 to move downward toward the lower support seat 13. While the lifting seat 1 approaches the lower support seat 13, the rubber ring seat 2 in the annular cavity 3 squeezes and fixes the outer wall of the cable. By repeating the above operations, the other section of the cable is fixed in the same way. Then, the staff connects the lifting seat 1 and the lower support seat 13 at both ends of the cable through the horizontal adjusting rod 10, and fixes them through the adjusting nuts 6 at both ends of the horizontal adjusting rod 10, so as to ensure that the position for the outer insulation layer repair by the sheath splicing mechanism at the connection of the two sections of the cable is in a horizontal state, and at the same time, it can also prevent the repair position from being affected by external forces, thus completing the end support treatment of the two sections of the cable.

[0049] The repair and shaping mechanism is arranged between the lower support seats 13 and is used to accelerate the shaping process of the repair position of the cable insulating sleeve spliced by the sheath splicing mechanism.

[0050] The repair and shaping mechanism includes aluminum alloy fins 9. A plurality of aluminum alloy fins 9 are equidistantly and fixedly connected to both sides of the middle part of the outer wall of the metal sleeve 5. An acceleration cavity is formed between adjacent aluminum alloy fins 9. Arc-shaped metal plates 4 are arranged on both sides of the middle part of the outer wall of the metal sleeve 5, and the inner walls of the arc-shaped metal plates 4 are respectively connected to the aluminum alloy fins 9 at the corresponding positions. The inside of the arc-shaped metal plate 4 is a hollow cavity.

[0051] When the repair and shaping mechanism is started, when the sheath splicing mechanism repairs the outer insulation layers of the two sections of the cable, the high temperature in the high-temperature repair material in the repair cavity 15 is conducted out to the external environment through the metal sleeve 5, thereby accelerating its shaping in the first step. Then, the temperature and heat conducted out of the repair cavity 15 to the outside are absorbed by the aluminum alloy fins 9 outside the metal sleeve 5 and then conducted to the arc-shaped metal plate 4 on the same side again, so as to expand its heat dissipation area. And since the acceleration cavity formed between adjacent aluminum alloy fins 9 can accelerate the speed of the air passing through the external environment, the heat generated by the repair material in the repair cavity 15 can be taken away to the greatest extent by the accelerating air flow, thereby promoting the shaping of the cable repair position.

[0052] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
